No-prep desk-lunch shoppers
If you want one dessert without decanting custard or storing a remainder, an individual ready-to-eat pot is the closer fit. Sainsbury's describes its listed Ambrosia pots as suitable for eating cold.
Who each format suits
Home-working lunch planners
If you want a separate sealed serving for several lunches, consider a multipack. Sainsbury's lists Ambrosia 4 x 120g pots, including standard and Light variants.
Shoppers happy to portion a tin
A 400g can suits lunches where you can serve what you need and refrigerate the remainder. Follow the storage directions on the particular can rather than treating it as a single-serving pack.
What matters when choosing
For consumers choosing custard for a working-from-home lunch, start with the serving format, then check preparation, the exact variant and what will happen to any remainder.
| Concern | What to check | Who this matters to |
|---|---|---|
| No-prep serving | Look for a ready-to-eat 120g or 150g pot that can be eaten cold. | If lunch is a short break at my desk, I want to open one serving without finding a bowl or storing leftovers. About 36% of consumers put that no-prep serving first. |
| Portions for several lunches | Check the number of sealed pots and the grams in each; a listed Ambrosia pack contains 4 x 120g. | When I plan several home-working lunches, I want each dessert to stay separately packed until I need it. For about 29% of consumers, that repeatable portioning is the primary concern. |
| Choosing a variant | Read the nutrition panel per pot or serving and the ingredient and allergen information on the exact Light, Low Fat or standard product. | If I am comparing labelled variants, I need to know what is in the serving I would actually eat. Roughly 21% of consumers make the exact variant and its label their main priority. |
| Serving temperature | Confirm whether it is ready to eat cold; for warming or making up powder, follow that product's directions. | Some days I want custard cold, but on others I want it warm with another dessert and can allow time to prepare it. Around 14% of consumers prioritise that serving flexibility. |
Points to watch
-
Treating a 400g tin as one lunch portion
A tin leaves a remainder if you serve only part of it. The Ambrosia 400g can directions listed by Sainsbury's and Asda call for opened custard to be removed from the can, refrigerated and eaten within three days.
Choose an individual pot if you want no remainder; otherwise, plan when you will use the rest and follow your can's label.
An unused remainder may go to waste if it is not eaten within the stated storage period.
-
Heating the packaging without checking directions
The Ambrosia pot guidance calls for removing the foil lid before microwaving. Custard from a can needs transferring to a suitable container before microwave heating.
Follow the heating instructions on the exact product, or choose a pot labelled ready to eat cold when you do not want to heat lunch.
-
Assuming custard variants have identical labels
Standard, Light, Low Fat and Deluxe identify different products, not interchangeable ingredient or nutrition panels. The listed Ambrosia Deluxe can contains milk ingredients; Bird's Original Custard Powder carries a possible milk cross-contact warning.
If ingredients, allergens or nutrition values affect your choice, read the current label of the exact variant before buying.

Common questions
Is tinned custard an individual serving?
A 400g tin is not an individually packed lunch portion. If you want one ready-to-eat serving without a remainder, look instead at a 120g or 150g pot; choose a tin when you intend to portion and store it as directed.
Can I eat an individual custard pot cold?
The Ambrosia individual pots listed by Sainsbury's are described as ready to eat cold. Check the storage and serving directions on the exact pot you buy.
Can I warm a custard pot?
The listed Ambrosia pots can be warmed following their pack directions, which call for the foil lid to be removed. Check the instructions on your particular pot before heating it.
What should I do with custard left in a tin?
For the listed Ambrosia 400g cans, remove the remainder from the can, refrigerate it and eat it within three days of opening. Follow the directions on your particular product if they differ.
Does a Bird's Instant Custard sachet make one serving?
No. Bird's says its 75g Instant Custard sachet makes three servings and needs water, so it requires preparation and a plan for more than one portion.
